VALVE.

Specification of Letters Patent.

Patented July 24, 194 't.

Original application flied June 2, 1915, Serial No. 32,009. Divided and this application filed March 10,

Suffolk and Commonwealth of Massachusetts, have invented certain new and 'useful Improvements in Valves, of which the fol- This invention relates to of this class by which air may beadmitted to the various pipes in the spraying system so that all oil may be removed therefrom by means of the pump forming a part of said system.

The invention further consists in certain novel features of construction and arrangement of parts which will be fully understood by reference to the descriptionof the drawings and to the claims hereinafter given. I

For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invcntionconsists can be variously arranged and organized, and that the invention is not limited to the precise arrangementand organization of these instrumentalities as herein shown and described.

Of the drawings:

Figure 1 represents an elevation of the tank of a road oiler'to which is applied a valve embodying the principles of the present invention. I v Fig. 2 represents a vertical'section of the discharge pipe from the tank with the valve operating mechanism therefor, the valve being shown open. 1

Fig. 3 represents a similar section with the valve closed and the vent to the discharge pipe open.

Fig. 4 represents a plan view of the rearsame.

I apparatus for applying liquids to roads and valves adapt- Serial No. 155,100..

Similar characters designate like parts throughout the several figures of the drawings.

In the drawings, 10 is a .tank provided at the top with the filling dome 11 through which the tank may-be filled from any suitable source of supply located above said tank. The tank 10 is supported on cradles 12 made of flat metal bars'bent to form a seat for the tank with inwardly extending feet which are secured to a demountable frame 13.

The demountable frame 13 is supported on the chassis or frame 15 of a truck having the usual supporting wheels and an engine mounted thereonby which the rear wheels may be driven in any well-known manner.

Mountedon the frame 13 is the revoluble shaft 29 of a rotary pump30. Means is provided whereby the pump .30 may be operated by the engine when the-vehicle is moving over the road or may be thrownout of commission as desired. It is obvious, moreover, that when the vehicle is at rest and the engine is in operation, while the transmission mechanism is thrown out of commission in the usual manner, the pump 30 may be placed in commission at will and be driven by said engine, all as fully shown and described in the application, Ser. No. 32,009 filed by me June 2, 1915, of which application this application is a division.

The inlet side of the pump 30 is connected by means of a pipe 42 to a suction strainer 43 of any well-known construction, and a discharge strainer 44 of any desired type is connected to the discharge outlet of said pump by means of the pipe 45, said strainer which is connected to a, transverse pipe 50, the opposite ends of :iwhich are connected 'with the rearwardly -extending pipes 51,

'each of which has a valve 84 to control the discharge of material therethrough.

The'pipe 48 is connected to the member 53 secured to the bottom of the tank 10 by of a plurality of heating pipes 112 through heater chamber 113 situated at of the tank 10.

a discharge pipe 54, said member 53having avalve seat 55 with which coacts a closing valve 56 shown in Figs. 1', 2, and 3 of the drawings.

The valve 56 is mounted upon the lower .end of a tubular valve stem- 57 extending upwardly through the tank 10. The lower end ofthe stem 57 has a hearing at 58 and mounted on its upper end is a revoluble sleeve 59 prevented from endwise movement is open. When the valve 56 is closed the pet .cock is moved into the position shown 1n Fig. 3, thereby permitting the air to pass through the stem '57 into the discharge pipe 54.

On either side of and parallel to the stem 57 are distance rods 63 extending across the tank 10 and serving to strengthen the same, the ends of said rods 63 being positioned in the housing 58* and the flanged member 60*. 1 p

The pipe 45 also has leading therefrom a discharge pipe 64 having a cutoff valve 65 therein. The end of the pipe 64 is threaded to receive a hose through which the contentsof the tank may be discharged when it is desired to empty the tank without sending the material through the sprinkler systems. From the bottom of the strainer 44 I is another discharge nozzle 66 through which the material may be drained from the strainer. The discharge nozzle is normally closed by the valve 67. I

The tank 10 is provided at its frontend with a chamber 110 from which extend to and through a head 111 near the rear therewhich hot air is adapted to pass from the the rear end From the topof the chamber 110 extends an outlet pipe 120 to carry off the heat therein.

The suction strainer 43' has secured to its outer wall a valve 121 through which the tank 10 is adapted. to be filled with liquid, the valves 56 and 65 .at this time being closedv and the liquid passing through the strainer 43 and pipe 42 to the pump 30, from which it is forced through the pipe 45 to a valve 122 which is open,'an d then through the pipe 123 into the top of the tank 10, the valve 45 having been turned to communicate with said pipe 123.

When the oil spray system is in use the valve 65 is closed but if it is desired to empty the tank this valve 65 is opened and the valves 84 and 122 closed, the. valve 45 being turned to communicate with pipe 64. The.

liquid will then be discharged through the pipe 64. The end of this pipe is threaded and a hose may be attached thereto so that if the tank is filled with water a-stream may be forced therethrough for the purpose of putting out fires. While the pump 30 is in oper. ation, if any of the cutofi' valves are closed temporarily the liquid discharged from the pump 30 will pass through the bypass pipe 46 to the'inlet; side of the pump, the relief valve 47 permitting this operation when a predetermined pressure has been reached.

On each side of the tank'lO is a reservoir 126 adapted to contain kerosene; or some similar oil.. Fromeach reservoir 126 extends a pipe 127 having a valve 128 therein and the two pipes 127 both connect with thepipe 129 communicating with the discharge pipe 54 immediately below the valve 56. v

' Each of the reservoirs 126 is connected by pipes 139 toan air pump140 operated by a handle 141. By means of this pump 140 the oil in the reservoirs 126 is maintained at a pressure of 40 lbs. I Y

The tank 10 may-either be filled by pump suction, or' it may be filled by any. suitable gravity supply by removing the manhole cover 140 and filling through the opening by any suitable conducting hose or pipe.

Whenever it is necessary to stop the dis tribution of the oil for any length of time bofore the tank is entirely emptied, the

valve 56 is closed and the vent cock 62 is opened. The valves 84 are then opened and the pump 30 is run until the piping system is entirely free from material.

The circulating valve 122 is then closed and the kerosene oil valve 142 is opened, allowing a jet of kerosene oil to enter the pump and piping system, and the pump 30 is kept running until the kerosene oil forced through the piping system has thoroughly cleared the same.

The. draincocks 67 are then opened to permitr'the draining of the strainer casings 43 and 44.

One of the great advantages of the present invention is that means are provided whereby the entire pipe system may be thoroughly cleared of oil and the tank may be filled with water and the apparatus then used for watering the streets.

It is believed that the operation and many advantages of this invention will be fully understood from the foregoing description.

In a device of the class described, the combination of a tank provided with an outlet herefrom; a pipe from said outlet; a pump connected with said pipe; a valve for said outlet; a tubular member the upper end of which extendsthrough the tank casing and the lower end of which extends through the said valve and opens into said pipe; means cooperating with said tubular member for raising and lowering said valve; and a pet cock on the outer end of said tun bular member.
